Non-overridable methods (``private`` or ``final``) that don't access instance data can be ``static`` to prevent any misunderstanding about the contract of the method.

== Noncompliant Code Example
|
|
|
|

|
|
class Utilities {
|
|
private static String magicWord = "magic";
|
|
|
|
private String getMagicWord() { // Noncompliant
|
|
return magicWord;
|
|
}
|
|
|
|
private void setMagicWord(String value) { // Noncompliant
|
|
magicWord = value;
|
|
}
|
|
|
|
}

== Exceptions

When ``java.io.Serializable`` is implemented the following three methods are excluded by the rule:
|
|
|
|
* ``private void writeObject(java.io.ObjectOutputStream out) throws IOException;``
|
|
* ``private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException;``
|
|
* ``private void readObjectNoData() throws ObjectStreamException;``
